Brian Cain 87a9cbaed1 [compiler-rt][TySan] Add Hexagon target support (#191603)
Add shadow memory mapping for Hexagon (32-bit architecture) and enable
the TySan build for the Hexagon target.

Hexagon uses a 4-byte shadow entry (PtrShift=2) with the shadow region
at 0x80000000-0xBFFFFFFF (1GB). A 28-bit mask (kAppMemMsk) covers 256MB
of app address space; addresses differing only in bits 28-31 alias in
the shadow. kAppAddr is set to 0xC0000000 to size the mmap to exactly
the 1GB shadow region.
